PubChem CID: 171548
Molecular formula: C10H16N2O3S
IUPAC: 5-[(3aS,4S,6aR)-2-oxo-1,3,3a,4,6,6a-hexahydrothieno[3,4-d]imidazol-4-yl]pentanoic acid
Source: PC-BIOTIN
Database chemical reference; does not certify supplier vial, salt, isomer or formulation.
Mechanism
Vitamin B7/carboxylase cofactor; nutritional need is not a pharmacologic hair-growth stimulant.
Evidence and critical reading
Reported scientific and empirical uses
Replacement and nutritional context · Skin, hair and cosmetics
Marketed for hair/skin/nails and blends. Distinguish deficiency from cosmetic supplementation without deficiency.
Human evidence
Institutional review describes limited evidence for cosmetic promises without deficiency. A multivitamin biotin injectable blend was not validated.
Preclinical evidence
Do not equate mechanism, cell culture or animal work with a clinical outcome. The specific level is detailed in the evidence assessment.
Critical reading and limitations
Institutional review describes limited evidence for cosmetic promises without deficiency. A multivitamin biotin injectable blend was not validated.

Regulatory product labeling
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Human-study exposure
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Empirical handbook
No numerical human dose is assigned: reviewed sources did not verify a regimen attributable to this material, route and indication. Other molecules’ doses, animal exposures, vial amounts and dietary requirements are not substituted.
Regulation and safety
Jurisdiction-specific regulatory context
This record does not verify FDA/EMA authorization of the commercial identity. Where a specific medicine/product exists, jurisdiction/indication are detailed in cited sources; they do not transfer to supplier material.
Adverse effects and unknowns
Can interfere with immunoassays including thyroid tests/some troponin assays, causing misleading results. This is an analytical interaction, not only a drug interaction.
Contraindications
No universal contraindication list is attributed to every biotin product; confirm formulation/excipients.
A complete list must match the exact authorized product. For experimental materials without verified human labeling, a complete contraindication set is not established here. No list does not mean safety.
Interactions
Analytical interference with some immunoassays: thyroid/troponin results can be misleading. Not a conventional drug interaction.
Separate documented interaction, pharmacologic plausibility and unknown interaction. Absence of a blend trial does not establish compatibility.
Studies and trials
Selected studies
No selected studies are attributed in this record.
Trials attributed in the package
No trials are attributed in this record.
Trial registration does not establish efficacy or validate commercial material.
