Differences
No significant difference in meaning or usage. Both variants use the same scientific term. The wood from which it derives gave its name to the country Brazil, but the chemical name remains the same.
Connotations
Connotes historical craftsmanship, early global trade (especially from the 16th-18th centuries), and specialised laboratory use. No modern everyday connotation.
Frequency
Extremely rare in both varieties. More likely to be encountered in academic texts on dye chemistry, economic history, or botany in both the UK and US.

No, it would sound highly unusual and overly technical. Use words like 'scarlet', 'crimson', or simply 'bright red' instead.
Both are natural dyes used in microscopy. Brasilin comes from brazilwood, while haematoxylin comes from logwood. Haematoxylin is far more common in modern biological staining.
Very rarely, mostly replaced by more stable, synthetic dyes. It may see niche use in art restoration, craft dyeing, or as a pH indicator in some laboratory contexts.
