Chemical Structure
Description
The occurrence of 3-Methyl-5-ethyl-2,4-nonanediol is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Methyl-5-ethyl-2,4-nonanediol (CAS 6628-31-5), molecular formula C32H61NO2 and molecular weight 491.83 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Methyl-5-ethyl-2,4-nonanediol (C32H61NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 491.83 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 3-Methyl-5-ethyl-2,4-nonanediol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
