Chemical compounds are identified in many different ways including molecular formulas, chemical structures, generic, systematic, common, and trade names. This lack of clarity can cause frustration, delays, and even safety concerns. A CAS Number is a unique and unambiguous identifier for a specific s...
Chemical compounds are ambiguous with respect to other entities or terms (in particular abbreviations and short formula). Existence of naming variation: typographical variants (alternating uses of hyphens, brackets, spacing, etc.) and alternative word order. New chemical compound are discovered and desc...
The second type of polymer, wherein the hydrophilic group is part of the spine or backbone of the polymer, includes compounds having the general formulas for example: ##SPC4## or R3siO--(SiR2O)L[SiR2(OCpH2p)mO]n--SiR3, and ...
