Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
trans-4-(4-n-Pentylbenzoyl)cyclohexane-1-carboxylic acid (CAS 736136-21-3) is a high-purity analytical reference standard with the molecular formula C19H26O3 and a molecular weight of 302.41 g/mol.
Owing to a steroid core, a hydroxyl group, an ether linkage, trans-4-(4-n-Pentylbenzoyl)cyclohexane-1-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures trans-4-(4-n-Pentylbenzoyl)cyclohexane-1-carboxylic acid 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.
