Oxandrolone API Supplier India | CAS 53-39-4 | Bulk Steroid API

Oxandrolone is distinguished from every other compound in this catalogue by a single structural feature: an oxygen atom replaces the carbon at position 2 of the A-ring. That oxandrane structure is what gives the molecule its stability and its notably different metabolic profile compared with other 17-alpha-alkylated steroids.

Oxandrolone Specifications

Quality Documentation — What to Request

Assay by HPLC, loss on drying and related substances form the standard set. Because Oxandrolone is used in tablet formulation, request the particle size and flow characteristics if you are compressing directly, and confirm the loss on drying figure before blending. Moisture content outside specification causes more oral formulation failures with this API than assay variation does.

Import, Licensing & Logistics

Controlled in most jurisdictions and subject to import licensing. Oxandrolone attracts particular regulatory attention because of established medical use in several markets, which means documentation scrutiny at customs tends to be higher than average.

Who Buys Oxandrolone API

Licensed pharmaceutical manufacturers producing oral solid-dose preparations.

The Oxandrane A-Ring

Oxandrolone is the only compound in this catalogue where an oxygen atom replaces the carbon at position 2 of the A-ring. That oxandrane structure is what gives the molecule its stability and its distinct metabolic profile relative to other 17-alpha-alkylated steroids. Because the material goes into tablet formulation, loss on drying matters more than it does for injectable APIs: moisture outside specification causes more compression and blending failures here than assay variation ever does.

Stability, Storage & Retest

Esterified anabolic APIs are chemically stable as dry powders but hydrolyse slowly in the presence of moisture, which regenerates the parent steroid and shifts the release profile of the finished preparation. Store sealed with the original desiccant, and do not decant into secondary containers before use. Retest intervals are typically set at 24 to 36 months depending on the ester, and the retest date rather than a manufacture date should appear on the Certificate of Analysis.

Export Process & Lead Time

Controlled substance consignments require an import licence issued in the destination country before despatch, and in most cases a matching export authorisation from the Indian authorities. Build four to eight weeks into your schedule for this, since the export authorisation cannot be applied for until the import licence is issued. Air freight is standard; sea freight is rarely used for controlled APIs because of the extended chain-of-custody exposure.

Incoming Goods Inspection

Your incoming goods check should cover appearance against the specification, identification by IR or HPLC retention time against a reference standard, and assay. For esters, free parent steroid content is worth running on first receipt from any new source even if the Certificate of Analysis reports it, because this is the parameter that most often differs between the certificate and the material.

Frequently Asked Questions

What documentation comes with Oxandrolone API?

Batch Certificate of Analysis, product specification and SDS where available for the specific source, plus export documentation including country of origin certificate for international consignments.

What is the minimum order quantity?

MOQ depends on specification, packaging and destination. Send your requirement and we will confirm the applicable minimum with your quotation.

Can you ship Oxandrolone API to my country?

Import permissions differ by destination and several markets restrict this material. Confirm your national requirements before ordering and we will advise whether we can supply into that territory.

How is pricing determined?

Pricing reflects quantity, specification, packaging and destination. Send your full requirement rather than a quantity alone so the quotation is accurate.
