D-Chiro-Inositol Powder Specifications

Final batch results and applicable specifications are stated on the corresponding COA.

What Is D-Chiro-Inositol?

D-Chiro-Inositol (DCI) is a stereoisomer of inositol. It has the same molecular formula as other inositol stereoisomers, but its molecular configuration is different.

For ingredient procurement, this distinction is important. A specification simply stating “inositol” does not define which stereoisomer is being supplied. Purchasing documents should therefore identify the exact ingredient, CAS number, assay, and analytical method.

D-Chiro-Inositol is commonly specified separately when a formulation requires DCI rather than another form of inositol.

≥98% D-Chiro-Inositol for Formulation

The ≥98% HPLC specification provides a defined assay target for manufacturers developing nutritional products.

The powder format can be evaluated in:

Capsules

Tablets

Sachets

Stick packs

Powder blends

Nutritional premixes

Multi-ingredient formulations

During formulation development, manufacturers may assess powder flow, blending uniformity, dissolution behavior, particle characteristics, and compatibility with other raw materials.

The appropriate use level and finished-product specifications should be established by the manufacturer based on the intended product and applicable market requirements.

D-Chiro-Inositol vs. Myo-Inositol

D-Chiro-Inositol and Myo-Inositol are both stereoisomers of inositol, but they are different ingredients.

For supplier qualification and production records, the required form should be stated explicitly to avoid confusion between the two materials.

Quality Control

Gold Herb's D-Chiro-Inositol specification is built around measurable raw-material parameters rather than a purity claim alone.

Identity and Assay

The product is specified as D-Chiro-Inositol with an assay of ≥98% by HPLC.

Physical Inspection

The powder is checked against the agreed appearance specification before release.

Additional Testing

Depending on the customer's requirements, the quality specification may include parameters such as:

Moisture

Heavy metals

Microbiological limits

Other customer-specific testing

The required limits should be agreed before commercial production when a customer has a defined internal specification.

Batch Documentation

Each qualified commercial batch is associated with its relevant analytical documentation. A Certificate of Analysis (COA) can be supplied for customer review according to the applicable product specification.

HPLC Analysis

For a high-purity D-Chiro-Inositol ingredient, assay testing is an important part of raw-material qualification.

The standard product specification is ≥98% HPLC. When evaluating a supplier, buyers should compare the stated assay with the analytical method and corresponding batch documentation rather than relying on the headline purity alone.

For projects with customer-specific testing requirements, the analytical specification can be reviewed before an order is finalized.

Applications

D-Chiro-Inositol Powder is suitable for manufacturers working with nutritional and nutraceutical formulations.

Capsules and Tablets

The dry powder can be incorporated into solid dosage forms. Flowability, compression behavior, particle properties, and excipient compatibility should be assessed during product development.

Powdered Supplements

Sachets and stick packs may require particular attention to dissolution, blending uniformity, taste, and finished-product stability.

Combination Formulas

When D-Chiro-Inositol is combined with Myo-Inositol or other nutritional ingredients, clear raw-material identification helps maintain the intended composition throughout production.

Women's Nutrition

DCI is considered in women's nutritional and wellness formulations. Finished-product positioning, dosage, and claims must be determined according to the applicable regulations in the target market.

Documentation for Supplier Qualification

For procurement teams, technical documentation is often required before a new raw material can be approved.

Depending on the project, Gold Herb can provide or discuss:

Certificate of Analysis (COA)

Product Specification

Technical Data Sheet (TDS)

Safety Data Sheet (SDS/MSDS), where applicable

Batch information

Packaging information

If your company uses a supplier questionnaire or raw-material approval checklist, the required documentation can be identified during the initial inquiry.

Packaging and Commercial Supply

Standard packaging is available for both development and production requirements.

1 kg foil bag
Suitable for sample evaluation, laboratory work, and smaller formulation projects.

25 kg drum
Designed for larger production requirements and routine bulk purchasing.

For commercial projects, packaging can be coordinated according to order volume, transportation conditions, and customer requirements.

Storage and Shelf Life

Store D-Chiro-Inositol Powder in a cool, dry location and keep the container tightly closed.

The material should be protected from excessive moisture, heat, and contamination during storage and handling.

The standard shelf life is 24 months under the specified storage conditions. The applicable batch documentation should be followed for commercial storage and handling.

What B2B Buyers Should Confirm Before Ordering

Before selecting a D-Chiro-Inositol Powder Supplier, procurement and formulation teams should confirm the following:

Ingredient identity
D-Chiro-Inositol, rather than generic inositol.

Assay
The required purity and corresponding analytical method.

Quality requirements
Any additional limits for moisture, heavy metals, microbiological parameters, or other internal QC items.

Documentation
COA, specification sheet, SDS, and other required supplier documents.

Packaging
Required pack size and labeling information.

Quantity
Sample, pilot, first commercial order, or recurring bulk volume.

Destination
Country or market where the ingredient will be used.

Providing these details at the quotation stage helps reduce specification changes later.

Why Source D-Chiro-Inositol from Gold Herb?

For specialty nutritional ingredients, supplier selection involves more than comparing unit prices.

Gold Herb focuses on practical B2B requirements such as:

Defined product specifications

HPLC assay information

Sample evaluation

Batch COA documentation

Bulk packaging

Specification matching

Technical communication for formulation projects

Customers can submit their own raw-material specification for comparison before purchase. This is useful when the finished product has specific analytical, documentation, or packaging requirements.
