Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3ar,6ar)-3a,6a-dimethyltetrahydropentalene-2,5(1H,3H)-dione 21170-10-5 cis-Tetrahydro-3a,6a-dimethylpentalene-2,5(1H,3H)-dione.
(3ar,6ar)-3a,6a-dimethyltetrahydropentalene-2,5(1H,3H)-dione 21170-10-5 cis-Tetrahydro-3a,6a-dimethylpentalene-2,5(1H,3H)-dione (CAS 21170-10-5) is a high-purity analytical reference standard with the molecular formula C10H14O2 and a molecular weight of 166.22 g/mol.
The molecular framework of (3ar,6ar)-3a,6a-dimethyltetrahydropentalene-2,5(1H,3H)-dione 21170-10-5 cis-Tetrahydro-3a,6a-dimethylpentalene-2,5(1H,3H)-dione (C10H14O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (3ar,6ar)-3a,6a-dimethyltetrahydropentalene-2,5(1H,3H)-dione 21170-10-5 cis-Tetrahydro-3a,6a-dimethylpentalene-2,5(1H,3H)-dione meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
