ETH-LAD (100mcg Blotters) Limited Stock
ETH-LAD (7-ethyl-lysergic acid diethylamide) is a semi-synthetic lysergamide distinguished by an ethyl substituent at the 7-position of the indole ring. Originally prepared in the mid-20th century as part of broader work on ergoline chemistry, it has remained a comparatively uncommon lysergamide but is valued as a structurally well-defined reference within modern analytical panels.
In contemporary laboratory settings, ETH-LAD is typically considered within the broader family of lysergic acid derivatives and is often examined alongside other substituted lysergamides such as AL–LAD and PRO-LAD. Its inclusion in method-development and screening work allows researchers to:
• Compare LC-MS(/MS) and LC-HRMS fragmentation behavior across a series of ergoline-based analytes;
• Evaluate chromatographic retention and separation for substituted lysergamides under different stationary phases and elution conditions;
• Investigate solution and blotter stability, potential degradation pathways, and sample-handling effects in analytical workflows;
• Explore how ring substitution at the 7-position influences analytical properties relative to other ergoline derivatives.
