This range covers 482 CAS-numbered products. Describing them individually would be less useful than characterising the range, because the structural composition tells you in advance which kind of specification questions you will be dealing with. Among entries for which we hold structure data, 82% are organic and 18% inorganic; the most frequent elements are H, O, C, N, Cl, Si, and the dominant functional groups are oxygen-bearing, nitrogen-bearing, metal-containing.
Compositionally the range splits cleanly by polarity: 26% of entries fall on the hydrophilic or water-dispersible side, 10% sit near the hydrophilic-lipophilic balance where emulsification matters, and 24% are lipophilic to the point that they need a compatible solvent before entering an aqueous phase. . A further 40% of entries carry no logP value and are excluded from the polarity split. Molecular weights are concentrated at 200~320 g/mol (32%); below 120 g/mol (21%); 320~500 g/mol (18%). Reading these figures together is usually enough to predict whether a substitution within this category will work at all.
For qualification purposes the practical consequence is that a single default grade rarely serves the whole category. Where an incoming standard or a downstream process defines the requirement, state it at enquiry stage: the usable subset of this range narrows sharply once the standard is fixed, and we can supply against it directly.
