While dansyl chloride derivatization works well for HPLC determination of primary amines, can anyone tell me for sure if it will work for a secondary amine? Or for that matter a tertiary amine as well? Thanks so much.

It's been many years since I played with this, but:

"As an aromatic sulfonyl chloride, Dns-Cl reacts with primary and secondary amino groups even at a slightly alkaline pH; at higher pH with phenols, imidazoles, and slowly even with alcohols"

from "Handbook of Derivatives for Chromatography", Blau & King, pg 350; Heyden (1977).
