Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
5337-61-1 6-heptyl-3-(3-methyl-2-butenyl)gentisaldehyde AR-1H1779 (CAS 5337-61-1), molecular formula C21H44O2 and molecular weight 328.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5337-61-1 6-heptyl-3-(3-methyl-2-butenyl)gentisaldehyde AR-1H1779 (C21H44O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 328.57 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.
