(2S,3R,4S)-2-Methyl-3,4-dihydro-2H-pyran-3,4-diyl diacetate CAS 91926-31-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2S,3R,4S)-2-Methyl-3,4-dihydro-2H-pyran-3,4-diyl diacetate.

(2S,3R,4S)-2-Methyl-3,4-dihydro-2H-pyran-3,4-diyl diacetate (CAS 91926-31-7), molecular formula C10H14O5 and molecular weight 214.22 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (2S,3R,4S)-2-Methyl-3,4-dihydro-2H-pyran-3,4-diyl diacetate (C10H14O5) 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 the polarity and ionization state of its functional groups, 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.

CATO manufactures (2S,3R,4S)-2-Methyl-3,4-dihydro-2H-pyran-3,4-diyl diacetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
